SIDE-BOARD LOCK.

- To all whom it may concern:

Be it known that I, EDWARD CRAIG, a citizen of the United States,residing at Albion, in the county of Edwards and State of Illinois, haveinvented certain new and useful Improvements in Side-Board Locks, ofwhich the following is a specification.

This invention has relation to side board locks for wagon bodies, andhas for its object to provide a lock of simple structure which may beapplied to the standards usually mounted upon the bolster of a runninggear for the purpose of engaging the members applied to the outersurface of the side board for holding the same effectually in positionwith relation to the standard and the bottom board.

Further objects and advantages will appear in the following description,it being understood that various changes in form, proportions and minordetails of construction may be resorted to within the scope of theappended claims.

For a full understanding of the invention reference is to be had to thefollowing description and accompanying drawing, in which;

Figure 1 is a fragmentary vertical sectional view through the portion ofthe wagon, showing the application of my improved lock for the sideboard. Fig. 2 is a front elevation thereof partly in section. Fig. 3 isa vertical transverse sectional view taken on the line 33 of Fig. 2.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingby the same reference characters.

As illustrated in the accompanying drawing the lock includes a member 1which is adapted to be applied to the outer surface of a side boardindicated at 2. This member is provided at a point betweenits ends andat its outer side with a socket 3 having at its lower portion a shoulderor lip 4. Below the said lip 1 the member 1 is provided at its outerportion with a curved shoulder 5. At its upper end the member 1 isprovided with an abrupt shoulder 6.

To the side of the standard 7 is attached a plate 8 having upon its sidea gudgeon 9. A member 10 is pivoted upon the gudgeon 9 and is providedwith a cam end 11 adapted at times to engage the shoulder 5 and forcethe member 1 in a downward direction. A pawl 12 is pivoted to the member10. The

said pawl may be pivoted to the side of the member 10 or may be pivotedin a recess 13 provided at the inner side of the said member 10. A bolt14 is passed longitudinally through the gudgeon 9 and a washer 15 islocated upon the outer portion of the said a bolt and bears against theside of the pivoted member 10. The bolt 14 also passes transverselythrough the standard 7 and is provided at its opposite end with anysuitable securing device, as for instance a nut as s shown. At its freeend portion the pivoted member 10 is provided with a shoulder 16 adaptedto fit snugly over the shoulder6. At its outer side the member 10 isprovided with a depression 17 which is adapted to receive theintermediate portion of a bail 18 which is pivoted to the member 1.

By this arrangement it will be seen that when the side board 2 ispositioned against the standard 7 and the free end of the member 10 isswung in an upward direction and the free end of the pawl 12 is engagedwith the lip 4: that the said pawl will draw the standard 7 and the sideboard 2 to which it is attached in a downward direction so that thelower edge of the said. side board will be firmly seated against thebottom of a wagon body, or against the bolster which supports thestandard 7. At the same time the eccentric portion 11 of the member 10will bear down against the upper side of the shoulder 5 and force themember 1 in a downward direction. When the member 10 is completelyclosed against the member 1 the shoulder 16 of the member 10 will fitsnugly over and upon the shoulder 6 of the member 1. Then thebail 18 isswung in a downward direction so that its intermediate portion entersthe depression 17 provided at the outer side of the upper portion of themember 10. Thus the parts are effectually locked in position. To removethe side board from against the standard 7 the operation above describedis reversed.

Therefore it will be seen that a simple and an effective mechanism isprovided for securely holding the side board of a wagon body in positionwith relation to a standard mounted upon a bolster and that the partsmay be easily and quickly manipulated for the purpose of removing theside board.

Having thus described the invention, what is claimed as new is:

1. In combination with a side board and a standard, means for lockingthe side board with relation to the standard comprising a.

member adapted to be applied to the outer surface of the sideboard, saidmember having a socket provided with a lip, a plate adapted to beapplied to the standard, a sec- 7 end member pivotally mounted upon theplate and having a hooked pawl adapted to enter the socket of the firstmentioned memher and engage the lip thereof, and means" lip, said memberhaving below the said lip a curved exserted portion, a plate adapted tobe applied to the standard, a second member pivoted upon the plateandha-ving a hooked pawl adapted to enter the socket and engage the lip,the said second member having an eccentric end adapted to engage theexserted port-ion upon the first mentioned member and force the same ina downward direction, and means carried by the first mentioned memberfor engaging the second mentioned: member and holding the same in closedposition with relation thereto. 3. In combination with a side board anda standard, means for locking the same comprising a member adapted to beapplied to, the outer surface of the side board and hav- .ing at itsouter side a socket provided at its lower end with a .lip, said memberhaving at its outer side below the said socket a curvedexserted portionwhich is provided at its upper end with a shoulder, a plate adapted tobe applied to the side of the standard and having a gudgeon, a secondmember pivoted upon the gudgeon, 'means for holding the second member inposition upon the gudgeon, a pivoted pawl carriedgaging the free endportion of the second i mentioned member and holding the same in closedposition against the first mentioned member. 7

In testimony whereof I aflix my signature in presence of two witnesses.
